To al zul/1,0m, it may concern: centrally to the upper side of the cross-bar 1 Beit known that I, EDWARD T. HARLOR, a is a wooden filling-piece 2, the ends of which citizen of the Uni-ted States, residing at H arare cut out or concaved', as shown at 3, to 55 ri'sburg, in the county of Franklin and State form bearings or seats for the inner ends of 5 of Ohio, have invented acertain new and usethe 'whiietree-sections, (indicated at 4.)

The sections 4are ously in opposite directions, motion imparted composed of metal, and the portions 5 thereof 65 to one of the sections or ends being communi. are provided with through-openings 6 for the x 5 4cated to the opposite section or end through reception of pivot-boltsS, which pass through an interposed connection.

v 5o Referring to the drawings, 1 designates the rear of the filling-piece 2 and having its ends "l cross-bar of a-'pair of shafts to which the imbent upward at an angle and extended proved whiflietree is to be attached. Secured through openings in the ears 14. The upper portions of the openings are eountersunk to receive nuts or fasteners 1G, which set into the recesses formed by countersinking the ears, thus leaving no objectionable projection. By the construction just described it will be apparent that when one of the whffietree-sections is vi'brated corresponding motion may be communicated to the other section by means'of the interposed connectingrod 15, so that as the outer end of one section is swung forward the corresponding end of the other section is caused to swing rearward.

The outer end of each whiflletree-section is provided with a trace' fastener or holder 18, which is constructed of spring-wire. A piece of spring-wire' is bent at its central portion to form an eye 19, whichlies against the under side of the whiftletree-section and is se-V cured by a suitable fastener 20. The termi-A nals of` the wire are then extended inward, as shown at 21, then bentat the points 2 2 and extended in opposite directions and formed lwith U-shaped bends 23, which embrace the side edges of the WhifHetree-section. After forming the U-shaped bends the terminals are bent at the point 24 on the upper side of the whifletree-section and extended, in substantially parallel relation outward toward the end of the section. At the point 25 the terminals are given an upwardly-extending U-shaped bend 26 and then extended downward to form a trace-retaining lip 27, which enters and passes partially or wholly through an opening28 nea-r the end of the whilletreesection. The terminals are then bent or recurved upon themselves andA extendedv upward, as shown at 29, andthe extremities thereof are bent outward laterally, as shown at 30, to form a lip or extension by means of which the end of the spring trace-fastener may be raised and lowered to admit of the i application of the trace to the whifetree-section and its removal therefrom.

From the foregoing description it will be apparent that I have provided a whiflietree which is practically noiseless in operation and which is capable of long use without material Wear. By having the points of connection of the connecting-rod to the whiiiletree-section substantially at right angles to a line drawn through the pivots of the two sections the sections mayswing simultaneously and easily without causing any binding of the parts. The ears 14 also form stops which cooperate with the projecting ends or corners of the filling-piece 2, so as to limit the swinging movement of the sections, one of the ears limiting the swinging movement in one direction and the other ear limiting the swinging movement in the opposite direction. The construction also provides for readily attaching and detaching the traces.

I-Iaving thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. The combinationwith a cross-bar or other suitable support, of a pair of whifletree-sections having disk-shaped innerends pivotally 'mounted on the cross-bar, a rod pivotally confilling-piece' cooperating to form limiting-A stops for regulating the amount of swing of the whiiietree-sections. i

3. The combination with a cross-bar or other support, of a pair of whiliietree-sections pivotall y mounted thereon and having diskshaped inner ends, a wooden iilling-piecesecured to the cross-bar and having concaved ends which partially embrace and Iit snugly against the inner ends of the whiiiietree-sections, annular or disk-shaped bearing-plates interposed between the whiffletree-sectionsand the cross-bar, bearing sleeves or collars,

passing through the sections and resting upon said plates, securing-bolts passing through the whi'letree-sections, collars or sleeves, plates and cross-bar, and aconnection between said sections causing` them to swing simultaneously', substantially as described.

4. The combination with a whiiiietree, of a trace-fastener composed of spring-wire bent at its central portion to form an eye arranged beneath the end of the whiftletree and designed to receive a suitable fastener, the U- shaped embracing portions extending around the side edges of the whitfletree, longitudinal portions extending outward therefrom toward the end of the whiiiietree, an arched or U-shaped portion extending upwardly above the whiffletree, a depending portion outside of said arched or U -shaped portion engaging an opening near the end of the whifletree, and a terminal lip extending laterally outward from the end of the fastener, substantially as and for the purpose described.

In testimony whereof I ax my signature in presence of two witnesses.
